Title: Velvet cutting machine - knife on pivot arm loaded by strong spring towards retracted position
Inventor: GIERSE FRANZ-JOSEF DR ING
IPC: D06C13/08
Filed: 1972-05-29
Abstract: Purely mechanical action releases knife from engagement with fabric faster than electromagnetic action when cutting force is too high or too low, enabling higher cutting speeds to be used. The knife arm is pivoted together with a measuring arm which is held in ca the same vertical pos. by a spring, and carries a latch which is released by adjustable stops ahead or behind when the measuring arm moves too far forward or backward with too low or high a cutting pressure. Releasing the latch allows the string spring to pivot the knife arm away rapidly.

Title: Plastic net material - manufactured by extrusion through reciprocating dies
Inventor: GAFFNEY BERNARD J DR
IPC: B29C48/05
Filed: 1972-10-20
Abstract: A thermoplastic polymer such as polypropylene is melt extruded under pressure through a series of die orifices to form 'net-like' structures. One set of dies is arranged either in a circular pattern or in a side-by-side relationship and the plastic extruded from them. Separate plastic streams are extruded independently from other dies so that these second streams cross the first set in a plane normal to it. The separate streams are allowed to set at the points of contact so giving the net-like pattern. To further facilitate the operation at least one of the dies reciprocates vertically. The dimensions and spacings of the strands may be controlled by altering the orifice size and die positions. In an extreme case sheet like products can be produced having a series of longitudinal protruding ribs.

Title: Control of oxygen and sulphur in molten steel - by determn. of discontinuity in solidification curve of test block
IPC: G01N33/20
Filed: 1974-01-23
Abstract: The use of a differentiated solidification curve for determn. of impurities, esp. oxygen and sulphur, in molten steel during refining in arc- or open hearth furnaces. During melting, or after tilting, a sample of 1-2 litres of steel is drawn off to form an even-sectioned test-piece (e.g. a cube or a cylinder where the height is equal to the dia.) in a mould surrounded by an inert material to retard the cooling rate. A thermocouple is inserted in the centre of the molten sample and a differentiated cooling curve obtd. The growth of dendrites stops after a period of time, indicated by a discontinuity in the curve, and after this interval solidification continues. By sectioning the test-pieces and comparing the structure with the cooling curves it is found that primary dendritic formation ceases at the discontinuity and random solidification occurs after this point. The time which elapses before the discontinuity occurs is related to the amt. of impurities in the melt, esp. oxygen and sulphur, an increase in impurities causing a redn. in the time and vice versa. The cooling curves can thus be correlated with the purity of the molten steel and the size of the test-piece can be related to the size of castings produced.

Title: Letter dispensing mechanism from stack - has additional feeler following feed rollers emitting call signal to switchgear
Inventor: RAPPARLIE HANS
IPC: B65H3/04
Filed: 1974-03-02
Abstract: A rotary extractor is in permanent frictional engagement with the front item in the stack, and delivers the items past a barrier into a set waiting position, from which they are delivered to a pair of continuously driven feed rollers on receipt of a call signal, a feeler being mounted between barrier and feed rollers. The extractor is only switched on if the feeler is either free, or if a call signal is present at the control switch unit. Braking time on switching off the extractor is such, as is the distance between feeler and rollers, that each item is first thrust as far as the feeler only, and then brought within range of the rollrs on receipt of a call signal. The section of conveyor track following the rollres has a further feeler, whose output signal is fed to the control switch unit as a call signal for the successive and automatic dispensing of items.
